My A3 went into limp home mode on the journey back home tonight. EPC light on, power very limited, coolant temp on min and electric fans on full. I keep a Carista dongle in the car, so I scanned it when I got home and it returned four errors:
P00B7 - Engine Coolant Flow Low/Performance
P0116 - Engine Coolant Temperature Sensor 1 Circuit Range / Performance
P2556 - Engine Coolant Level Sensor/Switch Circuit
P2681 - Engine Coolant Bypass Valve Control Circuit/Open
I haven't opened the coolant tank to see if it's dumped out yet.
Thoughts? Water pump? Thermostat? Or dodgy sensor?
